Well, I personally came up with the connection of McDaniels and Duckett. I won't claim to be the absolute first, but I have not seen any such connection before.
It's not the first time Duckett has been connected to New England. I believe in previous threads discussing his trade, myself and others have mentioned New England as being a good fit and destination because of their offense and need at the position for a powerful young RB.
But I'm unaware of anybody making a connection between McDaniels and Duckett. I recall last year a few people connecting Duckett & Saban about a possible trade, surrounding whether the Dolphins would take a RB or QB in Round 1 last year, thinking that they could draft a QB and still get a quality RB.
But I did Google Josh McDaniels, Duckett, and trade, and saw nothing that connected the dots, so yes I would say I am the author of this rumor
